The invention relates to a steam cleaner, particularly to a steam cleaner that operates easily and generates steam stability.
BACKGROUND OF THE INVENTIONConventional floor steam cleaners comprise a steam head, a steam generator and an integral reservoir. Water from the reservoir flows thought the steam generator and is heated to form steam. Steam is useful in removing oil and sticky matter from a floor. Several methods exist to make the water flow into the reservoir. One method uses a valve to control the water inlet. When the valve is open, gravity causes water to flow into the reservoir. Another method uses a pump to control the flow of water. The above methods have drawbacks such as difficult operation, complex mechanical structure or unstable steam generation.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a portable floor steam cleaner that is light-weight and is prepared for operation quickly and easily.
The steam cleaner comprises a handle assembly, a pivoting connector, a reservoir, a steam head and an electric wire. The handle assembly comprises a grip and a lever. The pivoting connector is attached to the steam head. The reservoir is mounted detachably in the pivoting connector and is removed easily to fill the reservoir with tap water. Squeezing the handle assembly releases water from the reservoir into the steam head where steam needs to be generated to clean a floor.
